3, solidify of ultraviolet light of colophony of visible light solidify raised taller requirement to illuminant, raised solidify cost. Its the heel of Achilles is environmental protection security bad, function of thick film solidify not beautiful. To solve these two problems, the choice is better through function than ultraviolet ray safer visible light undertakes solidify, it is the heat that studies domestic and internationally all the time. Shanghai clear and Jiang Xianlong of ministry of technology of colophony of vinyl of high polymer limited company introduced colophony of a kind of new-style visible light solidify. The physical function from condensate and corrosion resistance can be OKer see, visible light solidify is compared cross oxide solidify commonly, function comparatives, much better even. Use visible light is not harmful to human body ultraviolet light, very safe. Its applied range is extremely wide, solidify is fast, the volatilization of styrene is fewer; Task is simple, need not add accelerant and solidify agent, improve manufacturing efficiency while, reduce construction cost substantially. According to net of not saturated colophony (Www.upr-e.cn) expert introduces, hopeful of development of resinous of solidify of this type visible light reduces vinyl fat colophony considerably of downstream enterprise shape construction cost. 4, of composite material of smooth solidify UPR is not saturated kind of main matrix that polyester colophony regards composite material as, have good machine function, electricity function and be able to bear or endure chemistry corrodes function, raw material is easy, treatment craft is simple, economic value is high, according to net of not saturated colophony (Www.upr-e.cn) expert introduces, its production and treatment industry development are very rapid. Technology of ultraviolet light solidify (UV solidify technology) have volatilize without inert dissolvent, solidify time is short, but the advantage that the traditional solidify technology such as microtherm solidify cannot compare, call technology of new generation green. Smooth solidify technology serves as energy-saving with environmental protection technology oneself is extensive application is in coating, printing ink, adhesive, presswork industry of plank, electron, imperceptible treatment and shape quickly wait for a lot of domains. Use solidify technology in composite material workmanship, not only can solve difficult problem of a few craft, and be helpful for the modern industry with large-scale automation producing, accord with requirement of contemporary environmental protection at the same time. Colophony radical the smooth solidify technology of composite material is UV solidify technology develop way newly again in recent years.
